Abstract

The invention discloses an artificial wetland system of a sponge city. The artificial wetland system comprises a reservoir, a rapid filter pool, a surface flow wetland, an MBR (membrane bioreactor) treatment tank and a downstream subsurface wetland, wherein water in the reservoir flows to the rapid filter pool through a pipe; during normal running, water in the rapid filter pool flows to the surface flow wetland through the pipe, water in the surface flow wetland flows to the downstream subsurface wetland through the pipe, and water in the downstream subsurface wetland is drained to a sponge body water system through a drain pipe; during abnormal running or when maintenance is required, the water in the rapid filter pool flows to the MBR treatment tank through the pipe, and water in the MBR treatment tank flows to the sponge body water system through the drain pipe. The artificial wetland system has the following advantages: treatment effect is good, and growing plants are not prone todeath and are easy to maintain; by arranging the MBR treatment tank, during abnormal running or when maintenance is required, purification can be performed by the MBR treatment tank, and shutdown ofthe water system or draining of untreated sewage is avoided.

Description

technical field [0001] The invention relates to a sponge city artificial wetland system, which belongs to the technical field of municipal engineering. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". Building a sponge city requires a "sponge body". The urban "sponge body" includes not only water systems such as rivers, lakes, and ponds, but also urban supporting facilities such as green spaces, gardens, and permeable pavements. Rainwater infiltrates, stores, purifies, and reuses through these "sponge bodies", and finally the remaining part of the runoff is discharged through pipe networks and pumping stations, which can effectively improve the standard of urban drainage systems and reduce the pressure of urban waterlogging. Among them, the wet...
